Provided is a wearable display device. The wearable display device includes a display panel including a plurality of pixel island groups arranged along a first direction, wherein each of the plurality of pixel island groups includes a plurality of pixel islands arranged along a second direction, each of the plurality of pixel islands including a plurality of sub-pixels arranged along the first direction; and the second direction is intersected with the first direction; and a slit grating disposed on a light-exiting side of the display panel, wherein the slit grating includes a plurality of slits arranged along the first direction and extending along the second direction, each of the slits being configured to exit rays emitted by the sub-pixels in at least one of the plurality of pixel island groups.

Wearable display device

The present disclosure relates to a light field display system including: a plurality of light field display modules spliced at an angle, wherein each of the light field display modules includes a display screen and a micro-lens array located on a light-emitting side of the display screen; a lens group, including a plurality of spliced lenses corresponding to the plurality of light field display modules on a one-to-one basis, wherein the lens group is located on a side, away from the display screen, of the micro-lens array and configured to form a plurality of first imaging faces corresponding to the plurality of light field display modules on a one-to-one basis on one side, away from the micro-lens array, of the display screen, and the plurality of first imaging faces are seamlessly spliced to form a plurality of second imaging faces seamlessly spliced on a side, away from the light field display module, of the plurality of first imaging faces, wherein the first imaging face is configured to display an upright virtual image of the corresponding light field display module.

Light field display system

The present disclosure provides an optical device, a module, an apparatus and a system for fingerprint identification. The optical device includes: a first lens array including a plurality of first lenses; a second lens array opposite to the first lens array, including a plurality of second lenses; and a light shielding element between the first lens array and the second lens array, the light shielding element including a plurality of light-transmitting apertures. Image focal planes of the plurality of second lenses, object focal planes of the plurality of first lenses, and the light shielding element are coplanar. The plurality of first lenses are in one-to-one correspondence with the plurality of second lenses and the plurality of light-transmitting apertures, respectively.
